With Qin Fengming's mind, he naturally would not agree so readily to Xi Qinglun's proposal. Since they had already fallen out, getting him to release the two of them so easily was nothing short of wishful thinking.
Qin Fengming had also thought matters through before agreeing so quickly to what Xi Qinglun had said.
Although the Yin-Yang Eight Trigrams Formation's power had greatly increased by now, it was still impossible to say that it could kill two Nascent Soul cultivators in an instant.
This place was more than two million miles from the various sects' outposts, so he naturally did not need to worry about the experts from their sects receiving their voice-transmission talismans. But if the two men were ruthless enough to know that survival was already impossible and self-detonate their physical bodies, it would be a fatal attack on the Yin-Yang Eight Trigrams Formation.
After pondering it, Qin Fengming had already thought of a method: using the Talisman Treasure he had obtained but never once used.
A Talisman Treasure was created when an Integration stage cultivator sealed part of the power of his natal magic treasure onto high-grade beast hide through a secret technique. As long as the Talisman Treasure was activated, it could display part of the power of the Integration stage cultivator's natal magic treasure.
Although it possessed only part of the power of an Integration stage cultivator's natal magic treasure, it was uncertain whether it could injure a late Nascent Soul stage Great Cultivator. But against a mid Nascent Soul stage cultivator, there was no doubt it would suffice.
Back then, in the Yinming Mountain Range of the Yuanfeng Empire, Qin Fengming had obtained a Talisman Treasure. Yet he had never used it, because activating a Talisman Treasure required a relatively long period of preparation.
